Database Initialization Parameters for Oracle E-Business Suite Release 12

#

# Oracle E-Business Suite Release 12

# Common Database Initialization Parameters

#

# The following represents the common database initialization

# parameters file for Oracle E-Business Suite Release 12.

# Release-specific parameters are included in the respective release

# section. The release-specific parameters should be appended to the

# common database initialization parameter file.

#

# There are numerous mandatory database initialization parameters.

# Their settings must not be altered. The use of values other than

# those provided in this document will not be supported unless Oracle

# Support has specifically instructed you to alter these parameters

# from their mandatory settings.

#

# Mandatory parameters are denoted with the #MP symbol as a

# comment. This includes parameters such as NLS and optimizer

# related parameters.

#

# The remaining (non-mandatory) parameters relate to either sizing or

# configuration requirements that are specific to customer environments

# or system capacity. A sizing table provides recommendations and

# guidelines based on the number of deployed and active Oracle

# E-Business Suite users. Customers can adjust these parameters as per

# their environment and system resource capacity.

#

# Database identification parameters

#

# The database identification parameters define the name of the

# database and the names of the database control files.

#

# The database name is established when the database is built, and

# for most customers it matches the instance name. It should not

# normally be necessary to change the database name, except for

# the purposes of database cloning.

#

# There should be at least two control files, preferably three,

# located on different volumes in case one of the volumes fails.

# Control files can expand, hence you should allow at least 20M

# per file for growth.

#

#

# Compatibility parameter

#

# See the appropriate release-specific section of this document for details of setting compatibility.

#

#########

#########

#

# _system_trig_enabled

#

# The _system_trig_enabled parameter must be set to TRUE.

# If _system_trig_enabled parameter is set to FALSE it will

#

# Multi-Threaded Server (MTS) parameters

#

# Most Oracle E-Business Suite customers do not need to use MTS,

# and the default configuration disables MTS.

#

# If MTS is used, it can have a dramatic effect on the SGA, as

# session memory, including sort and cursor areas, resides in the

# Auditing parameter

#

# There is a performance overhead for enabling the audit_trail

########

#

# Dump parameters

#

# The main dump parameters specify the location of the trace and core

# files, and will normally point to the appropriate trace directories.

# The max_dump_file_size parameter can be used to specify the maximum

# size of a dump file, to prevent a trace file using an excessive

# amount of disk space. (This can also be changed at session level.)

# Timed statistics

#

# On most platforms, enabling timed statistics has minimal effect

# on performance. It can be enabled or disabled dynamically at

# both system and session level.

#

# Timed statistics is required for use of SQL Trace and Statspack.

#

########

#

timed_statistics = TRUE

########

# Trace file accessibility parameter

#

# As the database machine should be in a secure environment,

# setting this parameter to TRUE is recommended in order to

# Consider the security implications of setting this to TRUE

# as trace files may include secure data in BIND variables.

#

########

#########

#

# Processes and sessions parameters

#

# A database process can be associated with one or more database

# sessions. For all technology stack components other than Oracle

# Forms, there is a one-to-one mapping between sessions and processes.

#

# For Forms processes, there will be one database session per

# open form, with a minimum of two sessions per Forms user (one

# for the navigator form, and one for the active form).

#

# The sessions parameter should be set to twice the value of the

# processes parameter.

#

#########

sessions = 400 # 2 x no. of processes.

db_files = 512 # Max. no. of database files.

########

#

# Cursor-related parameters

#

########

cursor_sharing = EXACT #MP

open_cursors = 600

session_cached_cursors = 500

########

#

# Cache parameters

#

# For Oracle 10g and 11g, the automatic SGA tuning option (sga_target)

# is required. This avoids the need for individual tuning of the different

# caches, such as the buffer cache, shared pool, and large pool. Use

# of the automatic SGA tuning option also improves manageability and

# overall performance.

#

# sga_target refers to the total size of the SGA. This includes

# all the sub-caches, such as the buffer cache, log buffer,

# shared pool, and large pool. The sizing table in the

# section Database Initialization Parameter Sizing contains

# sizing recommendations for sga_target.

#

# # When the automatic SGA tuning option is used to dynamically size

# the individual caches, it is recommended to use a Server Parameter

# file (SPFILE) to store the initialization parameter values.

# Using an SPFILE allows the dynamically-adjusted values to persist

# across restarts. Refer to the Oracle Database Administrator‘s

# Guide for information on how to create and maintain an SPFILE.

sga_target = 2G #MP

db_block_checking = FALSE

db_block_checksum = TRUE

########

#

# Log Writer parameters

#

# The log writer parameters control the size of the log buffer

# within the SGA, and how frequently the redo logs are checkpointed

# (when all dirty buffers written to disk and a new recovery point

# is created).

#

# A size of 10MB for the log buffer is a reasonable value for

# Oracle E-Business Suite. This represents a balance between

# concurrent programs and online users. The value of log_buffer

# must be a multiple of redo block size (normally 512 bytes).

#

# The checkpoint interval and timeout control the frequency of

# checkpoints.

#

########

log_checkpoint_timeout = 1200 # Checkpoint at least every 20 mins.

log_checkpoint_interval = 100000

log_buffer = 10485760

log_checkpoints_to_alert = TRUE

#########

#

# Shared pool parameters

#

# The shared pool should be tuned to minimize contention for SQL

# and PL/SQL objects. For Release 12, a reasonable starting point

# is a size of 600M and a 60M reserved area (10%).

#

########

shared_pool_size = 600M

shared_pool_reserved_size = 60M

_shared_pool_reserved_min_alloc = 4100

########

#

# cursor_space_for_time parameter

#

# Cursor space for time is an optimization strategy that

# results in holding pins on cursors and their associated

# frames/buffers for longer periods of time. The pins are held

# until the cursor is closed, instead of at the end-of-fetch

# (normal behavior). This reduces library cache pin traffic,

# which reduces library cache latch gets. Setting cursor space

# for time to TRUE can be useful for large Oracle E-Business

#

# Cursor space for time requires at least a 50% increase in the

# size of the shared pool because of the frames/buffers. If AWR

# or Statspack reports show that the waits for library cache latch

# gets are significant, and the latch gets are due to pin

# requests, then cursor space for time can be used to improve

# performance.

#

# It is important to note that library cache latch contention can

# be caused by numerous different factors, including the use of

# non-sharable SQL (i.e. literals), lack of space, frequent

# loads/unloads, invalidation, patching, gathering statistics

# frequently and during peak periods, and pin requests.

# Cursor space for time is designed to optimize the pin requests

# only, and will not reduce latch contention for other issues.

#

########

# cursor_space_for_time = FALSE # Disabled by default.

#########

#

# PL/SQL parameters

#

# The utl_file_dir parameter must be set as:

# utl_file_dir = <directory> ...

#

########

utl_file_dir = /ebiz/prodr12/utl_file_dir

########

#

# Advanced Queuing (AQ) and Job Queue parameters

#

# AQ requires the TM process to handle delayed messages. A number

# of Application modules use AQ, including Workflow. Job Queues

# enable advanced queue to submit background jobs.

#

# Starting from 10gR1, aq_tm_processes is auto-tuned.

# Omitting this parameter has not, however, been tested with

# Oracle E-Business Suite. The minimum required value is 1 and

# should be increased to resolve lengthy queues.

#

# Usually, job_queue_processes should typically be be set to a value of 2

# for optimal performance. However, the value can be tuned to meet the

# specific requirements of the Workflow module and customer needs,

# based on the number of job queue processes needed to handle AQ

# event messages and for Workflow notification mailers.

#

########

aq_tm_processes = 1

job_queue_processes = 2

########

#

# Archiving parameters

#

# Archiving parameters, including destination (optionally,

# multiple destinations in 10gR2 or 11g) may be specified.

#

########

LOG_ARCHIVE_DEST_1 = ‘LOCATION=/disk1/arc‘

LOG_ARCHIVE_DEST_2 = ‘SERVICE=standby1‘

########

#

# Parallel execution parameters

#

# Parallel execution is used by some Oracle E-Business Suite concurrent programs,

# including DBI programs and Gathering Statistics. AD will also use parallel

# execution when creating large indexes.

#

########

parallel_max_servers = 8 # Max. value should be 2 x no. of CPUs.

parallel_min_servers = 0

########

#

# Events parameters

# The following Oracle RAC related parameters should be set when running

# E-Business Suite in an Oracle RAC environment.

# Set cluster_database = FALSE if not using RAC

#########

cluster_database = TRUE #MP

#########

#

# Parallel Execution and Oracle RAC parameters

#

# It is recommended to set the parameters instance_groups and

# parallel_instance_group on each instance, to ensure that parallel

# requests do not span instances.

# For example, on instance1, set instance_groups=apps1 and

# parallel_instance_group=apps1. On instance2, set

# instance_groups=apps2 and parallel_instance_group=apps2, and so on.

#

#########

#########

#

# Private memory area parameters

#

# The automatic memory manager is used to manage the PGA memory. This

# avoids the need to manually tune the settings of sort_area_size and

# hash_area_size.

# The automatic memory manager also improves performance and scalability,

# as memory is released back to the operating system.

# System-Managed Undo Parameters

#

# Oracle E-Business Suite requires the use of System Managed Undo (SMU).

# This is more efficient than manually managed rollback segments,

# and reduces the chances of "snapshot too old" errors. It is also

# easier to manage SMU than the rollback segments it replaces.

# PL/SQL parameters

#

# The following parameters are used to enable the PL/SQL global

# optimizer as well as native compilation.

#

# PL/SQL native compilation is recommended for Oracle Database 10g or 11g or 12c based

# Oracle E-Business Suite environments such as Release 12. Interpreted mode is supported,

# and can be used with Oracle E-Business Suite. However, native compilation is

# recommended in order to maximize runtime performance and scalability.

# Compiling PL/SQL units with native compilation takes longer than using

# interpreted mode, because of the need to generate and compile the native

# shared libraries.

#

# If native compilation is to be used, uncomment the plsql_code_type = NATIVE

# line below. Note that in 11g, the parameters plsql_native_library_dir and

# plsql_native_library_subdir_count have no effect and are are not needed, as

# natively compiled code is now stored in the database, not a filesystem.

#

#########

#plsql_code_type = NATIVE #Uncomment if you want to use NATIVE compilation.

#

# Optimizer Parameters

#

# Release 12 uses cost based optimization. The following optimizer

# parameters must be set as shown, and should not be changed.

#

#########

_optimizer_autostats_job=FALSE #MP Turn off automatic statistics.

#

# Parallel Execution and Oracle RAC parameters

#

# It is recommended to set the parameters PARALLEL_FORCE_LOCAL

# on each instance, to ensure that parallel requests do not span instances.

# As of 11gR2, EBS customers must set the value of this parameter to TRUE

# and then are no longer required to set parallel_instance_groups and

# instance groups for the purpose of preventing inter-instance sql

# parallelism in RAC environments.

#

#

# Database Password Case Sensitivity

#

#

# Oracle E-Business Suite now supports Oracle Database 11g case-sensitive

# database passwords. This feature is available with Oracle E-Business Suite Release 12.1.1 or higher.

# Even though its deprecated in 12c, paramer value need this parameter to used for EBS.

# To enable case-sensitivity, set the parameter sec_case_sensitive_logon to

# TRUE, and if on a release prior to 12.2 also apply patch 12964564.

# The database recyclebin must be turned off to allow the cleanup phase of the

# This feature may still be used at other times.

#

#

# service_names, local_listener parameter

#

# To support online patching, Oracle E-Business Suite Release 12.2 introduces a

# new database service called ebs_patch.

#

# The service_names parameter specifies one or more names by which clients can

# connect to an instance. The instance registers its service names with the

# listener. When a client requests a service, the listener determines which

# instances offer the requested service and then routes the client to the most

# appropriate instance.

#

# local_listener setting is part of Auto-config templates and is required for

# listener registration of any non default (1521) ports.
